FACTORS THAT AFFECT A TEST’S UTILITY
PSYCHOMETRIC SOUNDNESS
COSTS
BENEFITS
Higher criterion-related validity of test scores for making a particular decision, the higher the utility of the test is likely to be
PSYCHOMETRIC SOUNDNESS
a reliable and valid test is a useful test
PSYCHOMETRIC SOUNDNESS
In the context of test utility, it refers to disadvantages, losses, or expenses in both economic and noneconomic terms.
COSTS

family of techniques that entails a cost-benefit analysis designed to yield information relevant to a decision about the usefulness of a tool assessment
UTILITY ANALYSIS
evaluates whether the benefits of using a test outweigh the costs
UTILITY ANALYSIS
It helps in making decisions regarding whether:
➔ one test is preferable to another test for use for a specific purpose
➔ one tool of assessment is preferable to another tool of assessment for a specific purpose
➔the addition of one or more tests to one or more tests that are already in preferable for purpose
➔ no testing or assessment is preferable to any testing or assessment
UTILITY ANALYSIS
an indication of the likelihood that a testtaker will score within some interval of scores on a criterion measure—an interval that that may be categorized as “passing”, “acceptable”, or “failing”.
EXPECTANCY DATA
WHAT DATA IS USE TO CONDUCT UTILITY ANALYSIS
EXPECTANCY DATA
It provides an estimate of the extent to which inclusion of a particular test in the selection system will improve selection
